- Optimal gain,
- Deep, precise bass,
- Rich mids!
Excellent gain, deep and precise bass, rich mids and silky highs, with remarkable overall definition and brilliance. Selected for symmetrical circuits and recommended for guitar amplifiers to improve overall response.
Ideal for clean sounds as well as sounds requiring bass power, like any modern preamp. Recommended for all positions in medium-gain amplifiers, or in high-gain amplifiers for V2+ positions.
For V1 in general, and especially for high-gain amplifiers or phono/audio amplifiers, we recommend the RT010 7025 Highgrade or the RT030 E83CC/7025 Highgrade.
The TAD 12AX7A-C valve can replace any 7025, 12AX7WA, 12AX7WB, 12AX7LPS, 12AX7EH, ECC83 or E83CC.
It is the number one choice of many brands such as
Boogie®, Brunetti®, Diezel®, Engl®, Fender®, Hughes & Kettner®, Koch®, Laney®, Marshall®
